So my check engine cam on a month ago after a backfire and just got around to fixing it. The codes were 1135 and something that said it was spark plugs. So I replaced bank 1 sensor 1 and all the spark plugs and this fixed the problem for about 60 miles "2 days" and the light came back on with p1150 now. I replaced that 1135 sensor with Bosch 9009. Anybody think I have something else
Going on or did the from sensor just happen to go out around the same time?

 

V6 or 4 cylinder engine?

P1135 is a code for an A/F sensor heater problem, Bank 1, Sensor 1. Bank 1 is the cylinder bank closest to the firewall, 1st sensor on exhaust pipe.

Code P1150 is for a sensor performance range problem, Bank 1 or 2, Sensor 1.

This code is for a car built to California emissions specifications. There is a sticker under the hood stating if the car was built to California or Federal specs.

Can't find a Bosch 9009 part, is this the correct brand and part number?

Guessing you may have used the wrong sensor. The new sensor solved the heating element issue but being the wrong part caused the other code.

 

6 cylinder is what I have. Sorry the part number was a
Denso 234-9009. I almost for sure the code I first got was bank 1 sensor 1. That what everyone told me at least. The code I got now p1150 everyone is saying is bank 2 sensor 1? That's all the info I got from these web sites.

 

Sorry for all the typing errors lol. I'm not very smart as it is, let alone using these stupid phones to write.

 

This morning I drove the car and the check engine light went off by it self but the car runs like crap when at a stop.

 

Check the sticker under the hood stating if the car was built to California or Federal emissions standards. The sensors may be different.

P1150 is specific to California emissions cars.

My error in my last post. You replaced the right sensor which seems to have solved the P1135 issues. Possible the car was built to Federal standards and the installed sensor was for a California car.
